Sam's club. I forget how much they were, but it was a LOT less. Well, I think the price IS higher, but you get 6 or 8 brush heads. I bought the Triumph there, too, it was around $100, BUT there are 2 brushing units in there! One for me, one for the wife. Only one charger though. Before I got the triumph, I had the Vitality, which is their $30 unit. I used it for about a year, and now the Triumph's has about a year and a half on it with no battery problems.
